Hi there, @Ginga_p. I appreciate you enclosing the photo, showing the pertinent information relating to your TV model and software.
I've deleted the image, as it also showed your serial number, which is unique to you (so best to conceal this on the public forum).
I'd recommend trying to update your TV's software via the Internet periodically. If you still don't get the option to auto-download to the newest software version after a couple of weeks, please get back to us or reach out to our TV & AV Team on 0333 000 0333 (open from Monday to Sunday from 8am until 10pm).
